Richard:

You must have done more than just change a WPA key.

First, I can't speak to the MytvTV issues and this is the wrong list for 
those questions anyway.

As for the pvrusb2 driver's refusal to start, it is complaining that the 
FX2 firmware size is wrong, which can happen if you have a more recent 
16KB-sized FX2 firmware image and an older driver which looks for only 
8KB firmware.

A little less than a year ago, the pvrusb2 driver was updated to handle 
the larger firmware image, but if you're running a pvrusb2 driver 
included from a Linux kernel, then that kernel must be fairly recent.

You said this was working before, so if the driver isn't working now 
then it's because either you somehow updated that firmware image or 
switched to a version of the driver that doesn't work with that 
firmware.  That's obviously more than just a change of a WPA key.  Maybe 
you swapped firmware at some point in the recent past but haven't 
rebooted the device since then?
